Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed quantity of qubits is allocated for error correction, then the error correction process is simple to manage, but the system cannot adapt to changing error rates and may waste resources or fail to correct errors effectively

Engineering Contradiction:

Improveadaptability of qubit allocationVSAvoidcomplexity of qubit management system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements dynamic qubit allocation where the quantity of qubits assigned to error correction changes in real-time based on observed error rates. The system monitors error characteristics and automatically adjusts the number of error correction qubits, transitioning from a static allocation model to a dynamic one that adapts to changing quantum system conditions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system employs feedback mechanisms by continuously monitoring error rates in the quantum system and using this information to adjust error correction resource allocation. The error rate measurements feed back into the allocation algorithm, which then modifies the number of qubits dedicated to error correction, creating a closed-loop control system that optimizes resource usage based on actual system performance.

Inventive Principle:

Principle #23Feedback

2Reliability

If more qubits are allocated for error correction, then error correction effectiveness improves, but the number of qubits available for quantum processing decreases

Engineering Contradiction:

Improveerror correction effectivenessVSAvoidquantum processing capacity

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system applies partial action by allocating only the necessary number of qubits for error correction based on actual error rates rather than over-provisioning. Instead of always dedicating a large fixed portion of qubits to error correction, the system dynamically determines the minimum required allocation, using fewer qubits for error correction when error rates are low and allocating more when needed, thus optimizing the balance between reliability and productivity.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The patent changes the parameter of qubit allocation quantity based on error rate conditions. By making the number of error correction qubits a variable parameter rather than a fixed value, the system can optimize the trade-off between error correction effectiveness and quantum processing capacity, adjusting the allocation parameter in response to changing system conditions.

Inventive Principle:

3Ease of operation

If manual qubit allocation is used for error correction, then resource utilization is easy to control, but real-time adjustments cannot be made in response to changing error conditions

Engineering Contradiction:

Core Design Contradiction:

Ease of operationVSExtent of automation

Solution Approach 1:

The system implements self-service automation where the error correction qubit allocation is automatically adjusted by the quantum computing system itself based on monitored error conditions. The system autonomously determines when to increase or decrease error correction resources without requiring manual intervention, while still maintaining operational simplicity through automated decision-making algorithms that respond to system conditions.
